Politicians asked to support campaign against mining on farms

State politicians and the Farmers and Graziers Association are being asked to say where they stand on the issue of mining on farms.

There are calls for the state's political parties and agricultural industry to support a campaign to keep mining companies away from farms.

The Tasmanian Public and Environmental Health Network recently joined the national Lock the Gate Alliance in its campaign against inappropriate mining.

The Network's spokeswoman Isla MacGregor says a farmer in the state's north has decided not to negotiate with companies wanting access to his property for mineral exploration.

Ms Macgregor says the State Government, the Opposition and the Farmers and Graziers Association need to say where they stand on the issue.

"The Tasmanian Public and Environmental Health Network does have a particular interest in the public and environmental health aspects of mining in Tasmania across the state and we're very concerned about a number of mining proposals in Tasmania on farmland," she said.
